In order to promote regulatory efficiencies, the Labor Department should hold a public hearing on its proposed prohibited transaction exemption which replaces the fiduciary rule that was vacated by the U.S. Court of Appeals for the 5th Circuit, said Sen. Patty Murray, D-Wash. The agency should consider including the Securities and Exchange Commission in the hearing "to ensure that both agencies and all affected stakeholders are on the same page," she said in a letter to the acting head of the department's Employee Benefits Security Administration.
